Did you added users to the job and then removed them to add others again?

Our counter usage is per user (not per mailbox because groups and so on can have mailboxes also). However, if you add users, do a backup, then it counts as 1 license. If you remove it afterwards, it remains counting as a license for the next 31 days

Hi Mike
We installed the Veeam O365 product and Licence
We created storage and then created a job
In the Job we selected "All Mailboxes"
this selected 571 Mailboxes.
Some of these are shared mailboxes, some are E3 O365 mailboxes (194) and some are E1 O365 mailboxes (75)
The Veeam Application reports that we are over the licence limit (200) by 38 mailboxes

I cannot determine how Veeam has arrived at the number of licences, somewhere in the application it has counted mailboxes and compared them to the licence.
All I want to do is see this information so I can check which mailboxes are being counted and which ones exceed the licence.

Indeed. I would have expected that the amount of over license would be 69 and not 38. Could you create a support call around this? (PS: What version are you using). Post the case ID here so I can follow up if necessary and the outcome after investigation with the support team. (This might need to get escalated to development or QC)

A Veeam O365 licence is provided with a grace amount of 20% (minimum grace count 20 users)
The original Veeam O365 licence was for 10 users and a grace count of 20, allowing for 30 mailboxes to be backed up.
A new licence was purchased for 190 users and this was installed. This gave a grace count of 38 users. The installation of this licence overwrote the original licence.
The two licences were merged on the Veeam Portal to produce a licence for 200 users with a grace count of 40 and this was successfully installed.
As part of the original installation all O365 mailboxes were added to the backup job - a total of 269 user mailboxes and 200+ shared mailboxes/resources.
However this was restrained to 240 by the Veeam licensing limit.
The Veeam O365 setup was changed to include just the 194 E3 Office 365 users, because some of the original count of Mailboxes included E1 licences they still have a Veeam license assigned and it takes 30 days to release unused licences so it still shows the licence is exceeded, in the job it shows 34 mailboxes not licensed as these are being used by old mailboxes and have not yet been released.
Veeam development have a tool which can manually reset the licence count. This requires a copy of the database and logs being provided to Veeam and the Veeam O365 services being stopped.
Note: these 194 mailboxes had to be added manually as there is currently no GUI option to select these, although Veeam does have a powershell reference guide which may allow this to be run as a batch job.

It would be helpful if the documentation could be updated with this info on licence counting

I looked into your case some time ago and discussed it with a Veeam support engineer. I think there was some miscommunication and I apologize for that. I couldn't understand how you succeeded in protecting 69 over license but in reality, it was only 240 so 38 over license (or similar to that, can't remember the exact numbers anymore )

Glad to see it became clear now, but could you do me a favor and tell me where you want to see changes? (https://helpcenter.veeam.com/docs/vbo36 ... tml?ver=15)
My feeling says it is rather clear in the documentation, but since I am pretty much heavily involved in this, I might just consider it understandable
So any feedback is appreciated

I have read the page you highlighted and now I know how it works the page makes sense.

It may be beneficial to add some or all of the following
===
Veeam O365 grants an additional grace period licence of 20% (minimum 20 Licences).
The grace period is 60 (?) days in which time the correct licence should be purchased. Increasing the Licenced users will require Licences to be merged on the Veeam Licensing Portal.
